Intellitron AA-3913 4:1 Current Balun

Intellitron: Expertly Built, Economically Priced

The Intellitron AA-3913 4:1 Current Balun is a robust and essential accessory for any radio operator, serving two vital functions. First, it efficiently transforms a 200-ohm balanced antenna load down to a 50-ohm impedance, making it a perfect match for standard coaxial cable. This makes it an ideal solution for feeding popular antennas like folded dipoles and 200-ohm collinear arrays. Second, it excels at suppressing common-mode RF current from flowing down the coax shield, effectively preventing unwanted "RF-in-the-shack" that can interfere with your equipment and cause operational issues.

Built to last, the AA-3913 is housed in a heavy-duty PVC enclosure with durable stainless steel hardware. It features 14-gauge stranded copper pigtails that connect directly to your antenna element, ensuring all your transmitter power stays where it belongs - on the antenna!
